Cute pictures and gliders
Please do remove the pjs from the cage - they look to be flannel rather than fleece, and flannel is very prone to unraveling. These babies do not need any more health issues - especially one that can be easily prevented, such as an injury that can come from loose threads/strings in the cage.
Secure the wheel to the side of the cage with a zip tie, fleece tie or twist tie. There are many dangers from a wheel allowed to move about the cage like that - injured tails, injured fingers, trapped gliders, etc. Another thing that is easy to fix. :)
